It seems that Sony BMG's DRM problems never end. A security flaw has been found in their latest patch.

Sony BMG is replacing a patch for its CD copy-restriction software after Princeton University researchers found a security flaw in the update.

Sony released on Tuesday a patch that would remove its XCP content protection software that had been found with a batch of 27 of its CDs. The XCP was reportedly automatically installing DRM software on hard drives when put into a computer's disc drive.

However, ZDnet reports that Princeton computer science professor Ed Felten wrote in his blog on Wednesday that the patch itself could open computers to attack by hackers.

Sony executives said Thursday that they are working as closely as possible with security professionals to address the issues identified by Felten, and would have a new patch available by midday that day.

"The security space is a dynamic one, as we have learned," said Thomas Hesse, president of Sony's global digital businesses. "Our goal is to be diligent and swift, and we have gone to experts to handle this issue."

Sony's ongoing troubles with DRM software highlight the delicate line that record labels and other content companies are walking in trying to protect their products from widespread duplication.
